According to Starwood’s complaint, Nassetta is said to be under “intense pressure” to deliver the financial returns expected by the Blackstone Group, the private equity firm that paid $26 billion for Hilton in 2007. The complaint further states, “Intense pressure — whether from Blackstone or otherwise — is no excuse for corporate espionage, and it is no excuse for the massive theft and widescale use of confidential and proprietary Starwood information.”

Starwood is looking to appoint monitors to make sure that Hilton complies with all injunctions, and it’s also seeking a court-imposed “time out” period during which Hilton wouldn’t be able to move forward with its luxury brands.
